I sat incredulous last week listening to Steve Ballmer display more out-to-lunchness than I've ever heard from a major CEO. His company, Microsoft (MSFT), only recently lost the battle of most valuable technology company to Apple (AAPL). He is presiding over the umpteenth reorganization of the company he has run for years, having succeeded his pal, Bill Gates. His online business, whose Bing search engine is making modest gains against industry leader Google, lost more than $700 million last quarter.

Yet here was Ballmer traveling down a semantical rabbit hole over the future of the PCs. In Ballmerworld, it doesn't matter that the PC is shrinking in relevance. Any device is a computer, and people will want to use Windows because they're so familiar with it. By the way, Windows 7, Microsoft's latest release, is crushing it, further proof that computer users love Microsoft.
